Phosphine complexes like OsN(PMe3)2(R2)Cl (R = CH2SiMe3) with chloride tram to nitride, and frans-phosphines and iraras-alkyls, have been made [191]. Me3NO (but not Ph3PO or C5H5NO) oxidizes a nitride group into a nitrosyl... 

Nucleophilic catalysis is also observed with iodide ions. Fluoride ion does not form nitrosyl fluoride under diazotization conditions, as is to be expected from Pearson s hard and soft acids and bases principle which was discussed briefly in Section 3.2. More recently, nucleophilic catalysis has also been shown to occur with thiocyanate ion (SCN ), thiosulfate ion (HS2Of), dimethyl sulfide, and thiourea (H2NCSNH2) or its alkyl derivatives (see below).

In the CH3CH=CH2- -NO+ complex, the nitrosyl cation retains the characteristic canted geometry indicative of strong 7tcc-7txo interaction (Fig. 5.46(c)). However, the electrophilic attack shifts toward the terminal C of the pi bond, away from the methyl substituent. Such anti-Markovnikov complexation is, of course, to be expected from the relative polarization of the propylene pi bond toward the terminal C (so that the 7tCc antibond is polarized toward the alkyl pi-donor).

The literature cited in this article covers references listed in chemical abstracts to the end of 1961 and in current chemical papers after that. A degree of selection has been exercised in omitting some references that are now of limited value. Although metal nitrosyls are included in the scope of this chapter, no kinetic data on their decomposition is available and they will not be considered further. The data on metal carbonyls is limited and will be dealt with in the first section. The decomposition of metal alkyls and aryls has been extensively investigated. These compounds will be discussed in groups based on the position of the central metal atom in the periodic table and, when warranted, a further subdivision will be made based on the attached organic radicals.
